Removal of the Tension Assembly
Replacing the tension assembly on a Kenmore sewing machine is an important step to ensure proper functioning and result in a stress-free sewing experience. The tension assembly consists of two main parts: a tension-regulating spring, which controls the tension in the upper thread, and a tension-regulating nut, which controls the tension in the lower thread. These two pieces work together to keep the thread tension balanced and the stitching tight.
To remove the tension assembly from the machine, first, prepare the area. Make sure to have all the necessary tools and parts available. Power off the machine and unplug it from the power outlet. Move to the work surface in a well-lit area for the best visibility.
Now, open the top of the Kenmore sewing machine and remove the screw from the tension assembly. Use a medium-sized blade to remove the tension lever from the machine. Remove the spring and the three tension regulator screws. Pull out the tension regulator screw, the tension spring, and the tension regulator nut separately.
Once all the components are removed, it’s time to replace the new tension assembly. Put the tension assembly into the machine, making sure it fits snugly in its place. Check the instruction manual for proper placement. Place the tension regulator nut, the tension regulator screw and the tension spring back in their respective places.
Tighten the tension holder, making sure the thread has enough room around the tensioner before putting the lever back into the machine. Make sure the lever is aligned correctly with the machine’s indexing knob. To prevent any damage, use the flat part of a Phillips head screwdriver when screwing it in.
However, for a foolproof replacement, it is best to contact a professional technician to guide you through it correctly and check if the screws are in place. Depending on the type of machine and tension assembly, the technician can also offer solutions to keep the tension assembly working longer in the future.
Testing the Replaced Tension Assembly
Once the tension assembly has been replaced, it’s time to test it. Make sure to have the sewing machine powered off, unplugged and the fabric on the machine before any test runs. Double-check for any lint or debris in the tension disk as this can cause tension issues.
Start the sewing machine and adjust the tension controller. Make sure to adjust the tension controller to its lowest point. Sew a single row of stitches. The thread should move evenly along the fabric without getting tangled or loose. If the tension seems too tight or too loose, adjust the tension controller accordingly.
If stitches appear uneven, the thread is getting tangled or the threads are too loose, then the tension needs to be adjusted. When the tension is just right, the needle will go in and out of the fabric smoothly and the bobbin thread should be evenly distributed.
It is best to test out the tension assembly a few times before starting with the actual project. This way, you can get the tension exactly how you want it. However, if there are any issues still present, the tension assembly should be properly checked once again.
Common Signs of Tension Problems
It is important to identify any tension issues before they cause more problems. Knowing the common signs of a faulty tension assembly can help to identify any problems quickly. If the bobbin threads are tangled and showing on the surface, if the upper and lower threads fail to meet each other, or if the fabric puckers, then it’s a sign the tension is too tight.
Loose threads that fail to stay in place and elastic that fails to retain its shape are signs that the tension is too loose. Uneven stitches and fabric puckerings are also signs of an improper tension assembly.
Adjusting the tension or replacing the tension assembly is recommended to resolve these issues. However, if any of the symptoms still persist, it is recommended by experts to consult a technician for proper repairs.
Preventative Measures
In order to prevent any tension issues, it is important to maintain the sewing machine regularly. This includes frequently checking and cleaning the tension disk, replacing worn-out parts, and taking the machine to a professional for regular maintenance.
The tension assembly should be checked for lint or debris accumulation and any other type of damage every few months. Additionally, keep a check on the thread for any fraying, as a badly damaged thread can also cause tension problems. Make sure to use only high-quality threads for your projects.
Finally, store your sewing machine in a secure, dust-free and moisture-free area. Make sure to lock the machine when not in use to prevent any accidents.
Replacement Parts for the Tension Assembly
Replacing parts for the tension assembly is usually straightforward. But it is best to purchase replacement parts only from trusted sources and authentic vendors. Always refer to the manual before purchasing parts, as wrong sized or incompatible parts can result in tension issues or even damage the machine.
The tension spring and tensioner nut should be replaced regularly to ensure the tension assembly is working smoothly. The tension regulator screw can also be replaced to keep the tension balanced during sensitive projects.
For a complete tension assembly, the parts should snap into the machine easily and the tension should be adjustable. A sturdy, durable tension assembly is recommended to prevent any future tension issues.
Safety Considerations
Whenever working with the tension assembly in a sewing machine, it is important to consider safety measures. Make sure to never disassemble the machine without consulting a technician first. Do not attempt repairs on your own if you are unfamiliar with the task.
Keep your hands away from the moving parts and always power off the machine and unplug it from its power source before any servicing. Avoid using too much force when removing or replacing the tension assembly. Use the correct tools for the job to avoid any damage.
Finally, always wear safety glasses to protect your eyes and follow all the instructions in the product manual. Don’t forget to consult a technician if there are any issues with the tension assembly or any other part.
Replacing Steps for Specific Models
Depending on the model of the Kenmore sewing machine, the steps for replacing the tension assembly might vary. Make sure to refer to the instruction manual for the specific model to have a better understanding of how to remove and replace the tension assembly.
For instance, in the Kenmore 14523 sewing machine, the tension assembly is a black cylinder witha knurled edge near the top. To replace it, the machine needs to be unplugged, and the presser foot needs to be removed first. Then, the motor cover needs to be taken off, followed by the unscrewing of the tension assembly.
Similarly, with the Kenmore 1755 sewing machine, the tension assembly is located on the right side of the machine, near the needle. To replace it, turn off the power and unplug the machine, remove the side face plate and lower the presser foot assembly. Make sure to refer to the manual for detailed steps specific to the model.
Additional Tools for Maintenance
Apart from the tension assembly, there are a few other tools that are needed for a full sewing machine maintenance. Make sure to have a few extra needles, thread, bobbins and cloth in hand for any repair jobs.
A quality lubricant is also necessary for proper functioning and longevity of the machine. Learn about the recommended lubricants and use them to reduce the wear and tear of your sewing machine. Quality cleaning kits are also essential to keep the machine free of dust and debris.
Finally, make sure to check that the machine is level and stable on a flat and secure surface. Wobbly and loose machines can cause cumbersome stitching and improper tension.
